系數、次數、指數是什么意思？

代數式的單項式中的數字因數叫做它的系數(coefficient)。單項式中所有字母的指數的和叫做它的次數。簡(jiǎn)介：討論數學(xué)問(wèn)題時(shí)，在與特定的變量(或未知函數)及其導數有關(guān)的表達式或方程中，與未知數相乘的已知函數或常數稱(chēng)為系數。在物理學(xué)﹑工程，電腦技術(shù)及其他方面，也廣泛使用系數這一名詞。如一個(gè)量的部分值與總值之比，或一個(gè)量的變化與另一些量的變化之間關(guān)系式中的某些有關(guān)的數，都稱(chēng)系數。這時(shí)在系數之前常冠以有關(guān)現象或事物的專(zhuān)名，如\"膨脹系數\"﹑\"石碳酸系數\"等。單項式中的數字因數也叫做這個(gè)單項式的系數.多項式中最高次冪項的因數叫做這個(gè)多項式的系數。單項數中的的數字因數為它的系數。

1.通常系數不為0.

2.在多項式中含有字母的項，該項的整數部分稱(chēng)作是該項的系數，不含字母的項稱(chēng)作常數項。如多項式：4ab-5c+6d-7中，4、-5、6分別是含有字母的項a、b、c、d的系數，而-7這項不含有字母，所以稱(chēng)作為常數項。

3.如式子中沒(méi)有數字，系數的默認情況下是為1或-1。例：-x系數：-1；x系數：14.次數指單項式中所有字母的指數的和。5.分數的系數，例：-3πxy÷2的系數為-3π÷2。

Beta (Coefficient)代表什么

同學(xué)你好，很高興為您解答！

Beta (Coefficient)：貝塔系數，評估一種證券系統性風(fēng)險的工具，用以量度一種證券或一個(gè)投資證券組合相對總體市場(chǎng)的波動(dòng)性。

貝塔系數利用回歸的方法計算。貝塔系數1即證券的價(jià)格與市場(chǎng)一同變動(dòng)。貝塔系數高于1即證券價(jià)格比總體市場(chǎng)更波動(dòng)。貝塔系數低于1即證券價(jià)格的波動(dòng)性比市場(chǎng)為低。

對于各個(gè)投資領(lǐng)域內的專(zhuān)業(yè)人員，包括基金經(jīng)理、證券分析師、財務(wù)總監、投資顧問(wèn)、投資銀行家、交易員等等，CFA非常重要；它直接證明了你的職業(yè)素養和能力，被投資業(yè)看成一個(gè)“黃金標準”,這一資格被認為是投資業(yè)界中具有專(zhuān)業(yè)技能和職業(yè)操守的承諾?？忌歼^(guò)CFA對自己將會(huì )有很大幫助。
